Dispersal of processors AMD Athlon (Thunderbird) and Duron
(Continuation)

On card Abit KT7 it was possible to reach more considerable results - frequency of the processor has increased more than in one and a half time. Maximum productivity in integer calculations is reached at a mode of 896 MHz = 115 MHz * 8, and in calculations with a floating point - at frequency of 910 MHz.

It is necessary to mark, that for reaching of high values of frequencies it was impossible to do without rise of a supply voltage of a kernel of the processor and input/output chains. In the following table modes in which rise of supply voltages was carried out are specified.

Some attempts of dispersal of the processor were unsuccessful: did not transit the initial test (POST), the operating system or the computer did not boot hung up during test passing. Variants at which at least transited POST, are described in the following table. From the presented data follows, that in most cases the problem of astable operation could be solved by rise of a supply voltage of the processor. It is obvious, that rise of a supply voltage of a kernel it would be possible to achieve still bolshej frequency processor operation. However it raises risk of its output out of operation.

Data on processor Athlon dispersal are more low presented. In spite of the fact that processor Athlon managed to be dispersed only to frequency 825 MHz, essential rise of productivity of system is reached.
